Life imitates Neal Stephenson: in his first novel, The Big U (which Neal himself rather unfairly dismissed as "juvenalia" at one point), there's a college fad in which women wear ski masks, at first because they don't want to be seen without their makeup during late-night fire drills, but then because it gives them license to wear outfits that they otherwise wouldn't want to be caught dead in. Other features of the book: campus sewer LARPing, giant rats, a rail gun, oldskool mainframe hacking, and a performance of the Toccata and Fugue in D minor that literally brings the house down.
